Seek out the 3rz knowledge thread and LiveOak for any questions/problems that arise. You are on THE forum for 3rz swap so you got that going for you. I'm more or less useless when it comes to 3RZ swap tech as I had a shop do mine because I couldn't have my truck down for that long. I have picked up knowledge for sure but best to go to the guys who actually did the swap themselves. LiveOak is the best I've seen so far.
Fiberglass came onto my radar as well. I decided against it for the same reason. Our trails up here are full of trail rash and they would get torn up. I decided to trim my factory metal instead and then add tube from my sliders to my bumpers. I think it is the proper decision.
